Great detector for the price. I use highway and city driving on my commute to work and gives very good alerts to instant on Radar. Not many false alarms and after few days of driving the same route you get to know what's a valid alert and what are signals from other devices being used in the area(i.e. door openers, microwaves and the like). Very happy with this detector, it is neat how you can personalize the warning signals. Easy to set and customize.

The easy figuring how it sets up......too easy. missing a COMPASS
